抄録

An entomophthoraceous fungus was isolated as the pathogen of the epizootic of the brown planthopper, Nilaparvata lugens, which occurred in Chikugo, Kyushu Island of Japan in autumn of 1975, and its morphological and cultural characters were studied. The conidiophores were branched or sometimes simple, the cystidia slender and the conidia elliptical to ovoid with a slight papillate base, containing one or numerous oil globules, and measured 32.7×14.8μ (collected from hosts) or 30.2×15.5μ (collected from cultures). Rhizoids and resting spores were not observed. The optimum temperature and pH value for cultivation on Sabouraud's medium were 25°C and pH 6.3 to 6.7. The conidial formation on Sabouraud's agar+pupal extract and the hyphal growth on Sabouraud's agar+egg yolk were better than those on Sabouraud's agar only. This fungus was identified as Entomophthora delphacis HORI; this was resembled to E. aphidis and E. dipterigena but distinguishable by the characters grown on the artificial media and by their host ranges.
